Abstract

This invention provides a radiator for new energy vehicles, relating to the field of automotive parts. The radiator includes a heat dissipation structure, with an upper water tank and a bottom water tank connected to its upper and lower ends respectively. Side frames are connected to both side walls of the heat dissipation structure, and connecting structures are provided on one side wall of each of the two side frames. By designing the heat dissipation structure and using multi-layer composite materials for the heat dissipation fins (copper + aluminum foil + copper), the high thermal conductivity of copper acts as a "thermal bridge," rapidly transferring heat from the flat tube to all corners of the aluminum fins. This significantly improves the thermal conductivity of the fins themselves, reduces the temperature gradient on the fins, and makes the surface temperature of the entire fin more uniform and heat exchange more complete. Furthermore, by setting multiple triangular particles on the side walls of the heat dissipation fins in the heat dissipation structure, numerous tiny reinforcing ribs are added to the surface, significantly improving the local rigidity and deformation resistance of the heat dissipation fins.

[0016] (III) Beneficial Effects

[0017] This invention provides a radiator for new energy vehicles. It has the following beneficial effects:

[0018] 1. In this invention, by setting up a heat dissipation structure, the heat dissipation fins in the heat dissipation structure are made of multi-layer composite material, using copper + aluminum foil + copper, and taking advantage of the extremely high thermal conductivity of copper as a "thermal bridge", the heat of the flat tube is quickly transferred to all corners of the aluminum fins, which greatly improves the thermal conductivity of the fins themselves, reduces the temperature gradient on the fins, and makes the temperature of the entire fin surface more uniform and the heat exchange more complete.

[0019] 2. In this invention, by setting a heat dissipation structure, and by setting multiple triangular particles on the sidewalls of the heat dissipation fins in the heat dissipation structure, and adding countless tiny reinforcing ribs to the surface, the local rigidity and anti-deformation ability of the heat dissipation fins can be significantly improved. The triangular particles can play a guiding role, guiding air to pass more smoothly through the heat dissipation fin channels, reducing flow separation and eddy current generation, reducing system energy consumption and noise. The coating layer is beneficial for pollutants to roll off quickly under the scouring of airflow or rainwater, achieving a self-cleaning effect. Furthermore, during the cleaning process, the first slider can be controlled to slide up and down inside the two first sliding grooves, thereby slightly assisting in the removal of the deposits on the sidewalls of the heat dissipation fins.

[0020] 3. In this invention, by setting a connection structure, when in use, the first connecting plate is connected to the frame, and the fixing bolt passes through the frame and the first connecting plate and is threaded into the inside of the second connecting plate. Under the buffering connection of the two buffer springs, the vibrations received during vehicle operation can be absorbed. At the same time, by utilizing the sliding connection of the second slider and the second slide groove, and cooperating with the connecting springs at the upper and lower ends, the overall impact of vibration can be reduced, resulting in a good buffering effect.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figure 1-6 As shown, this embodiment of the invention provides a radiator for a new energy vehicle, including a heat dissipation structure 2. The upper and lower ends of the heat dissipation structure 2 are respectively connected to an upper water tank 3 and a bottom water tank 1. Side frames 4 are respectively connected to the two side walls of the heat dissipation structure 2, and a connecting structure 5 is respectively provided on one side wall of the two side frames 4.

[0031] The heat dissipation structure 2 includes heat dissipation fins 203. First grooves 201 are respectively provided at the center of the front sidewall of the heat dissipation fins 203 near both edges. A first slider 202 is provided at the upper end of the center of the front sidewall of the heat dissipation fins 203. The center of the rear sidewall of the first slider 202 is slidably connected to the interior of the two first grooves 201. The heat dissipation fins 203 include two first thermally conductive layers 204 and one second thermally conductive layer 205. The second thermally conductive layer 205 is disposed between the two first thermally conductive layers 204. Multiple triangular particles 206 are fixedly connected to the two sidewalls of the outer first thermally conductive layer 204. A coating layer 207 is coated on the sidewall of the outer first thermally conductive layer 204. By making the fins in the heat dissipation structure 2 a multi-layer composite material, using copper + aluminum foil + copper, and utilizing the extremely high thermal conductivity of copper as a "thermal bridge," the heat dissipation structure 2 quickly dissipates the heat from the flat tube. Heat is transferred to every corner of the fins, significantly improving the thermal conductivity of the fins themselves, reducing the temperature gradient on the fins, making the surface temperature of the entire fin more uniform, and the heat exchange more complete. By setting multiple triangular particles 206 on the sidewalls of the fins in the heat dissipation structure 2, countless tiny reinforcing ribs are added to the surface, which can significantly improve the local rigidity and deformation resistance of the fins. The triangular particles 206 can play a guiding role, guiding the air to pass through the fin channels more smoothly, reducing flow separation and eddy current generation, reducing system energy consumption and noise. The coating layer 207 is set to facilitate the rapid rolling off of contaminants under the scouring of airflow or rainwater, achieving a self-cleaning effect. In addition, during the cleaning process, the first slider 202 can be controlled to slide up and down inside the two first sliding grooves 201, thereby slightly assisting in the removal of the deposits on the sidewalls of the heat dissipation fins 203.

[0032] The connecting structure 5 includes two second slide grooves 509, which are respectively located at the center of one side wall of the side frame 4. A second slider 506 is respectively installed inside the two second slide grooves 509. The two side walls of the two second sliders 506 are slidably connected to the two inner side walls of the two second slide grooves 509. A connecting rod 507 is connected through the center of the upper end face of each of the two second sliders 506. The upper and lower ends of the two connecting rods 507 are respectively fixedly connected to the centers of the upper and lower inner side walls of the two second slide grooves 509. Connecting springs 508 are respectively sleeved on the side walls of the two connecting rods 507 at the upper and lower ends of the two second sliders 506. The upper and lower ends of the four connecting springs 508 are respectively fixedly connected to the upper and lower inner walls of the two second slide grooves 509 and the upper and lower end faces of the two second sliders 506. An installation structure is fixedly connected to the center of the other side wall of each of the two second sliders 506.

[0033] The mounting structure includes a connecting frame 502, with a second connecting plate 503 fixedly connected to the other end of the connecting frame 502. Buffer springs 505 are fixedly connected to the center of the other side wall of the second connecting plate 503 near both sides. The other ends of the two buffer springs 505 are jointly fixedly connected to a first connecting plate 501. A fixing bolt 504 is inserted through the center of the other side wall of the first connecting plate 501. The other end of the fixing bolt 504 passes through the side wall of the second connecting plate 503 and extends into the interior of one side wall of the connecting frame 502. By connecting the first connecting plate 501 to the vehicle frame, and by using the fixing bolt 504 to pass through the vehicle frame and the first connecting plate 501 and threaded into the interior of the second connecting plate 503, the vibrations experienced during vehicle operation can be absorbed under the buffering connection of the two buffer springs 505. Simultaneously, the sliding connection of the second slider 506 and the second slide groove 509, along with the cooperation of the connecting springs 508 at both ends, reduces the overall impact of vibration, resulting in a good buffering effect.

[0034] The upper water tank 3 and the bottom water tank 1 are respectively provided with a first connecting pipe 6 and a second connecting pipe 8 through the center of the rear side wall near one side edge, so as to facilitate the filling of coolant into the interior.

[0035] Cooling fans 9 are respectively installed at the center of the rear side wall of the heat dissipation fin 203 near the two edges. Two connectors 7 are respectively installed at the upper and lower ends of the two cooling fans 9. The front ends of the eight connectors 7 are respectively fixedly connected to the upper and lower ends of the center of the rear side wall of the heat dissipation fin 203. The two cooling fans 9 and the eight connectors 7 are detachably connected.

[0036] The first thermally conductive layer 204 and the second thermally conductive layer 205 are made of copper and aluminum foil, respectively, and the coating layer 207 is made of polytetrafluoroethylene. The combination of copper + aluminum foil + copper can achieve better thermal conductivity and heat transfer. Polytetrafluoroethylene can reduce the adhesion of dust and insect remains on the surface and achieve a self-cleaning effect.

[0037] The two connectors 502 are L-shaped to achieve better auxiliary connection effect.

[0038] The bottom water tank 1 and the upper water tank 3 are detachably connected to the side walls of the heat dissipation structure 2, which facilitates disassembly and replacement during maintenance and repair.

[0039] Working principle: This application is a new energy vehicle radiator. By setting the fins in the heat dissipation structure 2 to be made of multi-layer composite material, using copper + aluminum foil + copper, and taking advantage of the extremely high thermal conductivity of copper as a "thermal bridge", the heat of the flat tube is quickly transferred to all corners of the aluminum fins, which greatly improves the thermal conductivity of the fins themselves, reduces the temperature gradient on the fins, and makes the temperature of the entire fin surface more uniform and the heat exchange more complete.

[0040] Multiple triangular particles 206 are set on the sidewall of the fins in the heat dissipation structure 2, and numerous tiny reinforcing ribs are added to the surface, which can significantly improve the local rigidity and deformation resistance of the fins. The triangular particles 206 can play a guiding role, guiding air to pass through the fin channels more smoothly, reducing flow separation and eddy current generation, reducing system energy consumption and noise. The coating layer 207 is set to facilitate the rapid rolling off of contaminants under airflow or rainwater scouring, achieving a self-cleaning effect. Furthermore, during the cleaning process, the first slider 202 can be controlled to slide up and down inside the two first sliding grooves 201, thereby slightly removing the deposits on the sidewall of the heat dissipation fins 203.

[0041] By connecting the first connecting plate 501 to the frame, and by using the fixing bolt 504 to pass through the frame and the first connecting plate 501 and threaded into the interior of the second connecting plate 503, the vibrations experienced during vehicle operation can be absorbed under the buffering connection of the two buffer springs 505. At the same time, the sliding connection of the second slider 506 and the second slide groove 509, and the cooperation with the connecting springs 508 at the upper and lower ends, can reduce the overall impact of vibration and have a good buffering effect.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
